Authorities said Segundo Padilla, an employee of J.A. Alexander Inc. in Bloomfield, was smoothing part of a 1.45 mile path of the East Coast Greenway link in Union County on the border between Union and Kenilworth when the accident happened.

Padilla had smoothed over approximately500 feet of trail off Springfield Road and into Lenape Park when the Ingersoll Rand roller he was operating apparently toppled off an edge.

Union County Police and the Federal Occupational Safety and Health Administration are investigating the incident to determine whether he was wearing a seat belt.

An autopsy will be conducted by the Union County Medical Examiner to confirm the cause of death.
